    A cross-sectional study was conducted to explore clincians' baseline knowledge, practice beliefs and acceptance of intravenous (IV)-to-oral antibiotic switching practice in Hospital Pulau Pinang. The factors most highly rated for antibiotic conversion were the ability to maintain oral intake (85.6%) and microbiology etiology (85.0%). Majority of the clinicians (76%) agreed with the traditional clinical rule that "patient should be afebrile for 24 hours before IV-to-oral switch". Specialists and consultants had the highest knowledge score among the clinicians. However, they were generally less positive about a guideline being integrated into practice.

    End stage renal disease (ESRD) patients have a much higher rate of cardiac disease and cardiac mortality as compared with the general population. Revascularisation such as coronary artery bypass grafting (CABG) may also carry a higher rate of complications and morbidity. We compared our ESRD patients who underwent CABG with the general population and ESRD population.

    Surgical site infection (SSI) remains a common postoperative morbidity, particularly in colorectal resections, and poses a significant financial burden to the healthcare system. The omission of mechanical bowel preparation, as is performed in enhanced recovery after surgery programmes, appears to further increase the incidence. Various wound protection methods have been devised to reduce the incidence of SSIs. However, there are few randomized controlled trials assessing their efficacy. The aim of this study is to investigate whether ALEXIS wound retractors with reinforced O-rings are superior to conventional wound protection methods in preventing SSIs in colorectal resections.

    Workers with musculoskeletal disorders undertaking Malaysia's return to work (RTW) programmes may experience challenges in occupational competence (OC) and negative emotional states (NES). This study aimed to measure and examines the OC and NES of the workers by comparing specific comparison groups and groups of different phases. A total of 76 participants were recruited from a national RTW programme and categorized into three groups based on different RTW phases: off-work (n = 22), re-entry (n = 31), and maintenance (n = 23). Self-report questionnaires consisted of the Occupational Self Assessment version 2.2 and the Depression, Anxiety and Stress Scale-21. Results showed that injured workers exhibited significantly lower OC in comparison with an international group with various disabilities. In contrast, there was significantly higher NES when compared with Malaysia's general population. Significant differences in OC and NES were also found between workers in the three RTW phases. In particular, OC and NES in the off-work and re-entry phases were significantly lower (OC) and higher (NES) than in the maintenance phase. Furthermore, there was a moderate, negative correlation between OC and NES in the off-work and re-entry phase groups. This indicated that low levels of perceived OC were associated with higher levels of NES.

    Body mass index (BMI) is a good indicator of nutritional status in a population. In underdeveloped countries like Bangladesh, this indicator provides a method that can assist intervention to help eradicate many preventable diseases. This study aimed to report on changes in the BMI of married Bangladeshi women who were born in the past three decades and its association with socio-demographic factors. Data for 10,115 married and currently non-pregnant Bangladeshi women were extracted from the 2007 Bangladesh Demographic and Health Survey (BDHS). The age range of the sample was 15-49 years. The mean BMI was 20.85 ± 3.66 kg/m(2), and a decreasing tendency in BMI was found among birth year cohorts from 1972 to 1992. It was found that the proportion of underweight females has been increasing in those born during the last 20 years of the study period (1972 to 1992). Body mass index increased with increasing age, education level of the woman and her husband, wealth index, age at first marriage and age at first delivery, and decreased with increasing number of ever-born children. Lower BMI was especially pronounced among women who were living in rural areas, non-Muslims, employed women, women not living with their husbands (separated) or those who had delivered at home or non-Caesarean delivery.

    A stable oral mucosa is crucial for long-term survival and biofunctionality of implants. Most of this evidence is derived from clinical and animal studies based solely on implant-supported prosthesis. Much less is known about the dimensions and relationships of this soft tissue complex investing tooth-implant-supported bridgework (TISB). The aim here was to obtain experimental evidence on the dimensional characteristics of oral mucosa around TISB with two different abutment designs.

    The influence of awareness, knowledge, and attitudes (AKA) on the health-related quality of life (HRQoL) of patients with epilepsy has not been widely established. The aims of this preliminary study were to (1) assess general AKA and HRQoL levels, (2) correlate AKA and HRQoL levels, and (3) compare the HRQoL of patients with epilepsy with different AKA levels. A cross-sectional sample of outpatients with epilepsy were recruited from the Neurology Clinic, Hospital Sultanah Nur Zahirah, Kuala Terengganu, Malaysia. Data analysis was carried out using the Statistical Package for Social Sciences Version 15 employing descriptive and nonparametric statistics. On written consent, included patients completed the Malay AKA Epilepsy and the Malay Quality of Life in Epilepsy-30 (MQOLIE-30) instruments. Across all patients, both AKA levels (median: 80.0, range: 0-170) and overall HRQoL (median 51.5; range 15-97) were moderate. Awareness was significantly correlated only with Seizure Worry (r(s)=+0.29, p<0.05), whereas Knowledge was not significantly linked to any domain. However, Attitudes was significantly correlated with all domains (r(s)=+0.35 to +0.47, p<0.01) except Medication Effects and Seizure Worry. Patients with good AKA levels (Total Score ≥ median) experienced significantly better Overall Quality of Life and Cognitive Functioning (p<0.05). Findings showed that AKA may play an important role in influencing patients' HRQoL, suggesting that epilepsy treatment efforts should also focus on enhancing AKA through epilepsy awareness to improve health outcomes.

    INTRODUCTION: The Multiple Sclerosis International Quality of Life questionnaire (MusiQoL) is a self-administered, multi-dimensional, patient-based health-related quality of life (HRQoL) instrument. With increasing prevalence of multiple sclerosis (MS) in Asian countries, a valid tool to assess HRQoL in those patients is needed. The aim of this study was to evaluate patient acceptability, content validity and psychometric properties of an Asian version of the English MusiQoL in Singapore, Malaysia and India.

    MATERIALS AND METHODS: English speaking patients older than 18 years of age with a defi nite diagnosis of MS were included. The self-administered survey material included the adapted HRQoL questionnaire, a validated generic HRQoL questionnaire: the short-form 36 (SF-36), as well as a checklist of 14 symptoms. We assessed the internal and external validity of the adapted MusiQoL.

    RESULTS: A total of 81 patients with MS were included in the study. The questionnaire was generally well accepted. In the samples from Malaysia and Singapore, all scales exhibited good internal consistency (Cronbach's alpha >0.70). Correlation to SF-36 was generally good, demonstrating high construct validity (P <0.001) in some aspects of the MusiQoL.

    CONCLUSION: The Asian adaptation of the English version of the MusiQoL in evaluating HRQoL seems to be a valid, reliable tool with adequate patient acceptability and internal consistency.

    Malaria remains a major health problem in Sudan. With a population exceeding 39 million, there are around 7.5 million cases and 35,000 deaths every year. The predicted distribution of malaria derived from climate factors such as maximum and minimum temperatures, rainfall and relative humidity was compared with the actual number of malaria cases in Sudan for the period 2004 to 2010. The predictive calculations were done by fuzzy logic suitability (FLS) applied to the numerical distribution of malaria transmission based on the life cycle characteristics of the Anopheles mosquito accounting for the impact of climate factors on malaria transmission. This information is visualized as a series of maps (presented in video format) using a geographical information systems (GIS) approach. The climate factors were found to be suitable for malaria transmission in the period of May to October, whereas the actual case rates of malaria were high from June to November indicating a positive correlation. While comparisons between the prediction model for June and the case rate model for July did not show a high degree of association (18%), the results later in the year were better, reaching the highest level (55%) for October prediction and November case rate.

    PURPOSE: This study aims to determine if continuous infusion (CI) is associated with better clinical and pharmacokinetic/pharmacodynamic (PK/PD) outcomes compared to intermittent bolus (IB) dosing in critically ill patients with severe sepsis.

    METHODS: This was a two-centre randomised controlled trial of CI versus IB dosing of beta-lactam antibiotics, which enrolled critically ill participants with severe sepsis who were not on renal replacement therapy (RRT). The primary outcome was clinical cure at 14 days after antibiotic cessation. Secondary outcomes were PK/PD target attainment, ICU-free days and ventilator-free days at day 28 post-randomisation, 14- and 30-day survival, and time to white cell count normalisation.

    RESULTS: A total of 140 participants were enrolled with 70 participants each allocated to CI and IB dosing. CI participants had higher clinical cure rates (56 versus 34 %, p = 0.011) and higher median ventilator-free days (22 versus 14 days, p MIC than the IB arm on day 1 (97 versus 70 %, p

    Perdana University Graduate School of Medicine (PUGSOM), the first graduate-entry medical school in Malaysia, was established in 2011 in collaboration with Johns Hopkins University School of Medicine (JHUSOM), an American medical school. This study compared learning environments (LE) at these two schools, which shared the same overarching curriculum, along with a comparator Malaysian medical school, Cyberjaya University College of Medical Sciences (CUCMS). As a secondary aim, we compared 2 LE assessment tools - the widely-used Dundee Ready Educational Environment Measure (DREEM) and the newer Johns Hopkins Learning Environment Scale (JHLES).

    The present study aims to examine the effects of a palm-oil-derived vitamin E mixture containing tocotrienol (approximately 70%) and tocopherol (approximately 30%) on plasma lipids and on the formation of atherosclerotic plaques in rabbits given a 2% cholesterol diet. Eighteen New Zealand White rabbits (2.2-2.8 kg) were divided into three groups; group 1 (control) was fed a normal diet, group 2 (AT) was fed a 2% cholesterol diet and group 3 (PV) was fed a 2% cholesterol diet with oral palm vitamin E (60 mg/kg body weight) given daily for 10 weeks. There were no differences in the total cholesterol and triacylglycerol levels between the AT and PV groups. The PV group had a significantly higher concentrations of HDL-c and a lower TC/HDL-c ratio compared to the AT group (P < 0.003). The aortic tissue content of cholesterol and atherosclerotic lesions were comparable in both the AT and PV groups. However, the PV group had a lower content of plasma and aortic tissue malondialdehyde (P < 0.005). Our findings suggest that despite a highly atherogenic diet, palm vitamin E improved some important plasma lipid parameters, reduced lipid peroxidation but did not have an effect on the atherosclerotic plaque formation.

    Cleaning newborn infants with coconut oil shortly after birth is a common practice in Malaysian labour rooms. This study aimed: (1) to determine whether this practice was associated with a significant decrease in the core temperature of infants; and (2) to identify significant risk factors associated with neonatal hypothermia. The core temperature of 227 randomly selected normal-term infants immediately before and after cleaning in labour rooms was measured with an infrared tympanic thermometer inserted into their left ears. Their mean post-cleaning body temperature (36.6 degrees C, SD = 1.0) was significantly lower than their mean pre-cleaning temperature (37.1 degrees C, SD = 1.0; p < 0.001). Logistic regression analysis showed that the risk factors significantly associated with pre-cleaning hypothermia (< 36.5 degrees C) were: (1) not being placed under radiant warmer before cleaning p = 0.03); and (2) lower labour room temperature (p < 0.001). Logistic regression analysis also showed that the risk factors significantly associated with post-cleaning hypothermia were: (1) lower labour room temperature (p < 0.001); (2) lower pre-cleaning body temperature (p < 0.001); and (3) longer duration of cleaning (p = 0.002). In conclusion, to prevent neonatal hypothermia, labour room temperature should be set at a higher level and cleaning infants in the labour room should be discouraged.

    A randomized controlled study was carried out on 96 preterm infants (< 37 wk) with birthweight less than 2000 g admitted to a neonatal intensive care unit. The aim was to compare the weight gain between preterm infants exposed to 12 h cyclical lighting (intensity of light: 78.4 +/- 24.7 lux, mean +/- SD) and those exposed to a continuously dim environment (5.9 +/- 1.9 lux). The exclusion criteria were infants with major congenital malformations or who needed continuous lighting for treatment procedure and care. From day 7 of life until discharge, 50 infants were randomized to receive 12 h cyclical lighting and 46 infants to a continuously dim environment. There was no significant difference in the mean birthweight (12 h lighting vs continuously dim: 1482 vs 1465 g, p = 0.8), mean gestational age (31.6 vs 31.4 wk, p = 0.6), median duration of hospital stay (28.5 vs 28.5 d, p = 0.8), mean age to regain birthweight (13.0 vs 12.9 d, p = 0.3), mean weight gained by day 14 (27.6 vs 36.2 g, p = 1.0), median weight gain per day (11.9 vs 12.2 g, p = 0.9) or median body weight on discharge (1800 vs 1800 g, p = 0.4) between the two groups of infants.

    CONCLUSION: Exposing preterm infants to either 12 h cyglical lighting or continuously dim environment did not have any significant effect on their weight gain during the neonatal period.

    When standing height (StndHt) cannot be assessed, arm span (AS) or sitting height (SitHt) has been used as surrogate variables for prediction of StndHt in adult caucasians and blacks. We examined (1) the relationship between StndHt, AS and SitHt among adult Chinese, Malays and Indians; and (2) whether anthropometry could explain the ethnic differences in lung volumes (as StndHt-adjusted lung volumes are known to differ significantly: Chinese > Malays > Indians). We recruited 1250 consecutive outpatients aged 20-90 years. Prediction equations of StndHt (with AS, SitHt, weight, age as predictors) for each subgroup of race and sex were formulated with multiple linear regressions. Equations with both AS and SitHt as predictors had the best goodness of fit (SEE = 2.37-2.85 cm, adjusted R2 = 0.67-0.87), as compared to equations with either AS (SEE = 3.00-3.91 cm, adjusted R2 = 0.58-0.80) or SitHt alone (SEE = 3.48-4.00 cm, adjusted R2 = 0.45-0.76). GLM general factorial analyses found that age- and weight-adjusted SitHt-to-StndHt ratios differed significantly among Chinese (0.539), Malays (0.529) and Indians (0.518). This paralleled the ethnic differences in lung volumes. The equations with both AS and SitHt as predictors provide the most accurate estimate of StndHt. Ethnic differences in upper body segment length may explain in part the lung volume differences.

    A study to determine the effect of antihelminthic treatment on growth and nutritional status was undertaken on 103 children in the second grade of primary school, 71 of whom were found to be infected with Ascaris lumbricoides or Trichuris trichiura. The median Ascaris and Trichuris intensities in the infected group were 19,600 (range; 0-488,000) and 2,800 (range; 0-84,600) eggs per gram of feces respectively. Forty-three children harbored both types of worm. Fourteen weeks after two 400 mg doses of albendazole were administered to infected children, the increases in weight, height, weight for age, height for age and weight for height were significantly higher among infected children than controls who were uninfected at baseline. The observed gains were independent of sex and socioeconomic status. Decrease in log transformed Trichuris intensity correlated with increases in weight (r=0.24; p=0.02) and weight for age (r=0.20; p=0.06) but decrease in Ascaris intensity did not correlate with increases in any of the anthropometric parameters. The results suggest that antihelminthic treatment has beneficial short-term effects on growth and nutritional status of a modest magnitude among early primary schoolchildren in the area.

    The aim of the present study is to investigate the influence of the CYP2D6*10 allele on the disposition of tramadol hydrochloride in Malaysian subjects. A single dose of 100 mg tramadol was given intravenously to 30 healthy orthopaedic patients undergoing various elective surgeries. After having obtained written informed consents, patients were genotyped for CYP2D6*10: the most common CYP2D6 allele among Asians by means of allele-specific polymerase chain reaction. The presence of other mutations (CYP2D6*1, *3, *4, *5, *9 and *17) was also investigated. Tramadol was extracted from 1 ml serum with an n-hexane: ethylacetate combination (4:1) after alkalinisation with ammonia (pH 10.6). Serum concentrations were measured by means of high-performance liquid chromatography. The pharmacokinetics of tramadol was studied during the 24 h after the dose. As among other Asians, the allele frequency for CYP2D6*10 among Malaysians was high (0.43). Subjects who were homozygous for CYP2D6*10 had significantly (P=0.046) longer mean serum half-life of tramadol than subjects of the normal or the heterozygous group (Kruskal-Wallis test). When patients were screened for the presence of other alleles, the pharmacokinetic parameter values were better explained. CYP2D6 activity may play a main role in determining tramadol pharmacokinetics. The CYP2D6*10 allele particularly was associated with higher serum levels of tramadol compared with the CYP2D6*1 allele. However, genotyping for CYP2D6*10 alone is not sufficient to explain tramadol disposition.
